MICHAEL J. O. MALLEY, OF CHICAGO, ILLINOIS.

ASBESTOS BASKET.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed Kay 1, 1918. Serial No. 94,840.

To all whom it may concern:

Be it known that I, MICHAEL J. O. MALLEY, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in AsbestosBaskets, of which the following is a specification.

My invention relates to improvements in baskets, and, more particularly,that form of basket used as a receptacle for waste paper.

It is the object of my invention to provide a construction of basket inwhich reinforced asbestos sheet or board is employed, whereby there isproduced a fire-proof receptacle.

The invention will be more fully understood from the following detaileddescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is a side elevation of one form of mybasket. Fig. 2 is atop plan view, aportion of the inner layer of the bottom being brokenaway to show the reinforcement. Fig. 3 is an enlarged horizontal sectionon the line 3 of Fig. 1. Fig. 3 is a similar section showing acorrugated sheet. Fig. 4 is an enlarged vertical section through onecorner of the basket shown in Figs. 1, 2 and 3. Fig. 5 is/a similar viewshowing a modified construction of the bottom. Fig. 6 is a similar viewshowing a still further modification of the construction of the bottom,and Fig. 7 is an enlarged section showing the construction of the upperrim of the basket. y

The form of basket shown in the drawings is of frusto-conical shape, thebody of the basket being formed of inner and outer plies 10 and 11,respectively, of asbestos sheet or board cemented together as by abinder composed of silicate of soda, or the like, and having sandwichedbetween them a sheet 12 of reinforcing wire fabric. Fig. 3, the seam ispreferably formed by lapping the asbestos sheet facings as illustratedat 13, the lap-joint being cemented. The bottom of the basket is formedof a pair of asbestos disks 14, 15, spaced some distance above thebottom of the side walls, as shown in Fig. 4, and reinforced by a pairof sheetmetal straps 16 arranged at right-angles and between the disks14, 15, each of the straps being turned downwardly and then upwardlyabout the lower edge of the side walls, as illustrated at 17, in Fig.4:. To complete the construction a U-shaped metallic rim 18 As shown in(Fig. 4), having its upper edges inturned, as at 19', 1s slipped overthe lower edge of the side walls and over the downturned ends II of thestraps, securing rivets 20 being employed to hold the parts in theirassembledposition. By the construction described it will be noted thatthe inner edge 19 of the bottom r m 18 forms a shoulder, or ledge, uponwh ch the bottom of the basket may rest, the rim furthermore serving assecuring and masking means for the reinforcing straps 16. p

The upper rim of the basket is preferably stiffened by an additionalannulus 21 cut from asbestos sheet, or board, and cemented 1n place, asshown inFig. 7. A U-shaped metallic upper rim 22, riveted in place as-at23, finishes the upper edge of the basket, this rim also preferably,having its edges inturncd, as at 24, the outer inturned'edge 21 servingto mask the lower edge of the stillemng strip 21, as is apparent fromFig. 7

The complete basket as above described, may be sub ected to any of theknown treatments for hardening and finishing the asbestos, as by dippingthe completed basket into a bath of earthy matter, such as a thin claymixture, and then into a bath of sodium silicate, by which process thesurface of the asbestos becomes coated with a firmly adher- 1ng layer ofearthy matter, which may be of any desired color, bound with the sodiumsilicate.

In Figs. 5 and 6 I have illustrated two modifications of theconstruction of the bottom of the basket. In both of these modi'fications the metallic rim, which forms the lower edge of the basket,has an inturned flange 30 which extends beneaththe bottom and serves tosupport the same. In Fig. 5 the bottom is shown as comprising upper andlower disks 31 and 32 of asbestos sheet, or board, inclosing betweenthem a disk 33 of sheet metal. The compound bottom thus formed issecured in place as by rivets 34 passing through the flange 30 of thebottom rim.

The construction of Fig. 6 is identical with that of Fig. 5, save thatthe sheet metal intermediate the bottom member 33 of the former figureis replaced by a perforate metallic reinforcement which may be in theform of a wire fabric 35, similar to the wire fabric 12 used forreinforcing the side walls.

In Fig. 3 I have shown the basket side wall as constructed ofcorrugated, reinforced sheet, designated 40, the"corrugations runninglongitudinally of the basket. This form of corrugated sheet is the sameas that shown and described in my prior application Serial No. 85,330,filed March 20, 1916, and is peculiarly useful and desirable in thepresent service by reason of its strength and stifi'ness.

While I have shown and described in considerable detail some specificembodiments of my invention, it is to be understood that these areillustrative only, and for the purpose of making the invention moreclear, and that I do not regard the invention as limited to thesedetails, nor to any of them, except in so far as such limitations areincluded within the terms of the following claim, in which it is myintention to claim all novelty inherent in my invention as broadly as ispermissible, in view of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:

In a basket of the character described, side-walls comprising aplurality of sheets of asbestos hardened by earthy matter and cemented.together and having sandwiched between them a foraminous metallicreinforcement, a bottom spaced above the lower edges of the side-wallsand comprising upper and lower sheets of asbestos having sandwichedbetween them metallic reinforcement, and a U-shaped metallic rimembracing the lower edges of the side-walls and extending upwardly andsecured to the said bottom for supporting the same.

It is hereby aertified that the name of the pawnuw in Letters Patent.No. 1,209,316, granted December 19, 1916, for an improvement in AsbestosBmkebs,"

was erroneously wribtan and printed "Michael J. O. Malley," whereas saidname should have been written and printed as Michael J. 0 Malley; andthat the said Letters Patent should be read with this correction tbareinthat the same may conform to the record of the case in tha PatentOffioe.
